To all whom it may concern:

Be it known that I, HARVEY E. 'Hnnsn, residing at Allentown, in thecounty of Lehigh and State of Pennsylvania, have invented certain newand useful Improvements in Mechanism for Operating Swinging Sashes,whereof the following is a specification, reference being had to theaccompanying drawings.

My invention relates to operating mechanism to be used in connectionwith sashes or transoms, especially where such sashes are wide, or arearranged in horizontal series.

Under these circumstances, it is desirable that the force tending toswing the sash or sashes, be applied at regular intervals in order toavoid torsional strain along the pivoting axis of the sash. To this end,my invention includes horizontal sliding bars with connections atsuitable intervals, where by motion of reciprocation of the bar istranslated into motion imparting to the sash the requisite swingingmovement.

In the accompanying drawings, Figure l, is an elevational View showingparts of one or more swinging sashes having my operat ing mechanismapplied thereto.

Fig. 11, is a perspective view showing a part of a sash and theoperating mechanism.

Fig. III. is a sectional view along the line 111, 111 of Fig. 1.

A framework 1,1, 1, incloses a long sash or series of sashes, involvinghorizontal members 2, and vertical members 3. These sashes are pivotedalong a horizontal axis by means of the pivots 4, mounted on lugs 5, setupon a horizontal member 6, which is in stationary relation to the sashframe.

The members 7, 7 are in like stationary relation to the sash frame andcarry slide bearings 8, 8, 8. 8, within which are mounted slide rods 9,and 10. In order to secure reciprocal motion of these two slide rods,their extremities are connected by chains 11, 11, passing around pulleys12, 12. At suitable intervals, there is setupon the slide rod 9, acollar 13, to which is attached the chain 14-, which passes around theguide pulley 15, and thence around the larger pulley 16, after which itreturns around a second guide pulley 17, and finds attachment upon acollar 18, set upon the slide rod 10. This chain is of suitable lengthand tension so that as the rods 9, and 10, reciprocate, the pulley 16,which is mounted upon an axis parallel to that upon which the sashswings, has impart ed to it, a motion of rotation. The means employedfor suitably mounting the pulleys 15, 1.6 and 17, will be suflicientlyiunderstood from the drawings without detailed description and may varyaccording to circumstances.

The pulley 16, has set upon it an arm 20, to the swinging end of whichis pivoted a link" 21, the far extremity of which is in turn pivoted tothe sash at 22. Similar pul leys 16, with chain and guide pulleys andwith an arm 20, and link 21, are set at convenient intervals along theentire length of the reciprocating rods 9, and 10, and at each suchpoint, by the elements which have been described alternatingreciprocation of the rods is translated into a thrust by the links 21,imparting to the sash or sashes to which they are pivoted an evenswinging motion upon the horizontal axis of said sash or sashes. Y

In order to communicate proper reciprocal 1 swinging motion. In suchcase it may be convenient to attach to the sash a longitudinal member10, to serve as acommon point of attachment for the pivoted ends ofthese links. Where a series of swinging sashes are arranged upon acommon horizontal axis, each one may have one or more points ofattachment depending upon the length of each sash and the number ofattachments necessary to impart to it an even swinging mo tion withouttorsional strain.

Having thus described my claim: I

1. The mechanism for imparting axial rotation to a swingin sash,consisting of two horizontal slide rods; means for obtaining alternatereciprocation thereof; a pulley set on an axis parallel to that on whichthe sash swings; a chain passing around the pulley with its extremitiesfast to the rods, wherer by the reciprocation of the rods rotates saidpulley; and an arm and link by which r0- tation of the pulley impartsswinging motion to the sash.

2. Mechanism for imparting axial rotation to parallel swinging sashesincluding in combination slide rods parallel to the axis on which thesashes swing; means for obtaining alternate reciprocation of said rods;brackets rigidly mounted in proximity to said rods; a pulley mounted ineach of said brackets in position between said rods; a pair of guidepulleys mounted in each bracket at right angles to the pulley; a chainpassing around the pulley and guide pulleys in each bracket with itsextremities fast to i the rods whereby the reciprocation of the rodsrotates said pulley; and connections whereby the rotation of each pulleyimparts swinging motion to a sash.

3. The mechanism for imparting axial rotation to parallel swingingsashes consisting of slide rods, parallel to the axis on which thesashes swing; means for obtaining alternate reciprocation of said rods;pulleys mounted rigidly and independently of said slide rods, set onaxes parallel to those on which the sashes swing; flexible meansattached to the slide rods and extending over the pulleys wherebyreciprocation of the slide rods imparts a simultaneous and equalrotation to the pulleys without lateral strain on the rods; andconnections whereby rotation of each pulley imparts swinging motion to asash.

In testimony whereof, I have hereunto signed my name at Philadelphia,Pennsyl- Vania, this 12th day of February, 1917.
